Pei Te Bao has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polyester compositions, and process for making articles therefrom
    Patent number: 10662325
    Abstract: The present invention relates to a polymer composition comprising a thermoplastic polyester and a propylene-based elastomer, wherein the propylene-based elastomer comprises propylene-derived units and 5 to 30 wt % of ?-olefin-derived units, and has a melting temperature of less than 120° C. and a heat of fusion of less than 75 J/g.
    Type: Grant
    Filed: June 1, 2018
    Date of Patent: May 26, 2020
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Ying Ying Sun, Yi Ping Ni, Pei Te Bao, Yi Zhou Shi, Xiaoyun Wang
  • Propylene-based polymer compositions for injection molding
    Patent number: 10344152
    Abstract: The present invention is related to a propylene-based injection molded composition made from a polymer blend comprising from 45 to 85 wt % of a polymer blend modifier having a weight average molecular weight of 10,000 to 100,000 g/mole and from 15 to 55 wt % of a propylene-based elastomer having a weight average molecular weight of from 100,000 to 300,000 g/mole, where the weight percent of the polymer blend modifier and the propylene-based elastomer are based on the total weight of the polymer blend. The polymer blend modifier comprises a first propylene-based polymer and a second propylene-based polymer, where the first and second propylene-based polymers are different and are individually selected from a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin.
